Fisher-Price video recorder PXL-2000
1987–1988
The PXL-2000’s innovation was its use of a standard audio cassette instead of the more expensive videocassettes. You could record about four minutes of black-and-white low-resolution video on each side of the cassette, but the high-speed tape rolling mechanism was so noisy that it ruined the sound quality. Also, it took six AA batteries to power the camera for roughly seven minutes. It only lasted a year on the market. Today it has become a collector’s item for its unique retro video characteristics.
